Completed two system tune up. Today included a downstairs system furnace tune up. I also preformed a complementary upstairs tune up as well for the miscommunication on failed inspection reports. Both up and downstairs condenser fuses need to be changed in order to pass inspection with the city of Frisco. New 50 amp fuse box and 25 amp fuses (upstairs furnace) needs to be replaced. Office will call and schedule work to be done. Filter size for downstairs system is 20x24x4 01/13 Conpleted installation of new disconnect boxes in order for units to ass inspection. Pictires attached.
